Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990164, here are decompositions:
- 13 + 990151 = 990164
- 127 + 990037 = 990164
- 151 + 990013 = 990164
- 163 + 990001 = 990164
- 193 + 989971 = 990164
- 277 + 989887 = 990164
- 337 + 989827 = 990164
- 367 + 989797 = 990164
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 990,164 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 990164 first appears in π at position 869,114 of the decimal expansion (the 869,114ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
